Kuka · KR C4 Controller
This fault occurs when an overvoltage condition is detected during the charging phase of the KPP/KSP drive. This can be caused by an excessively high mains voltage or an insufficient number of connected capacitors, posing a risk to sensitive components.
Click steps to track your progress.
Measure the incoming mains voltage — verify it is within the specified operating range.
Verify the number of connected capacitor modules is adequate for the system configuration.
Reinitialize the drive bus by cycling Power Off / Power On.
Check the KPP module for any status indicators.
Check the KSP module (improbable).
